APPAIt'IUS FOR MERGING BUTTER .ANB 'MILK'.

Application led November 4, 25908. Serial No.`460',991.

T o all whom it may concern.

Be it known that I, BENJAMIN N. Hawes, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in 4Apparatus .tor Merging Butter and Milk, of which the following is a specication.

This invention relates to an apparatus for emulsifying butter and milk, or merging butter and milk together.

The object of the invention is vto provide a simple and inexpensive apparatus i-or merging butter and milk, and one in which the parts may be readily assembled and taken apart.

In the drawings, Figure l is'a central sectional View 'of the apparatus; Fig. 2 is a side elevation; Fig. 3 is a. top plan view; and Fig. 4 is a central sectional view showing a modified form of mixer frame which acts in conjunction with the rotary mixer.

The numeral l designates the outer vessel which is preferably .cylindrical in shape and the numeral 2 designates the inner vessel.

The two vessels are spaced apart to form a water chamber 3. Soldered or otherwise secured to the bottom of the inner vessel, is a plug 4, having therein a depression 5, preferably conical in shape, for the reception of the conicai end of the shaft 6, of the rotary mixer 7. This mixer is provided with a plurality of oppositely extending arms 8 vpreferably elliptical in cross section, so as to present cutting edges 9. The top of the shaft is squared as indicated at 10 to it in a. correspondingly shaped opening 11 of a bevel gear 12 which has a boss 13 extending l through a circular opening 14, in the center of a support 15. The support 15 is provided with four arms 15', and 15.` Formed integral with the arms l5. are two standards 16, bifurcated at 17 to form bearings for the operating shaft' 18, to which is integrally attached a crank 19. The shaft is squared at 2() where it passes through the squared opening 21 irl/the beveled gear wheel 22, which is in mesh with the wheel 12. The shaft is held in position and the wheels are held in mesh by ya clamp 23, which bears at its central portion upon the shaft, and the clamp is bolted to the arms 15". The arms 15H are provided with elongated openings 24, either of which may receive the upper end 25 of a finger frame 26, the fingers 27 of is operated.

which project between the arms or blades of the -rotary mixer 7. The lower .end of the finger frame is stepped into a socket 28, which is soldered or otherwise secured to the inner receptacle, at or near the bottom thereof.

The numeral 29 designates the oppositely disposed brackets soldered or otherwise secured to the outside ot' the inner receptacle, which brackets are adapted to receive the downwardly extending tongues 1%() oi the arms 15"' ot' the support, whereby the said support is prevented from turning on the receptacle. y f

The outer receptacle is of considerably less height than the inner receptacle, and this made so ior the purpose oit prevent- 'zug the likelihood of water as it is being poured into the outer cylinder. 'from passing into the inner cylinder. 'The plug i extends slightly through lthe outer receptacle, preferably. and the two receptacles are preferably soldered together around the plug, asshown.

The arms 15 of the support are7 like-the arms 15 provided with depending tongues 3l which overhang the edge of the inner receptacle when the apparatus is assembled.

The plug l is preterablysquared as indicated at 32 to adapt it for use in conjunction with the modified form of finger frame 33 shown in Fig. 4. This finger frame is formed of a horizontal arm 34 and two oppositely disposed arms 35. cachot which latter arms is provided with a plurality of l lingers 86, through which the arms orblades of-the rotary mixer pass when the machine The arm 34 of the frame is provided with a squared opening 37 which fits' snugly over the squared end ofthe plug fl and the upper ends 37 of the frame extend through the openings 24 in the arms 15 of the supporty for the rotating mechanism.

Patented Sept. 7, '1909.

This frame, asin the ease of the frame 26,

may be readily removed after the product is made, so that the 4product may be easily removed from the inner receptacle and the apparatus parts be more readily cleaned.

in addition to soldering the inner reeeptacle to the outer receptacle, l provide short braces 38 whose ends are soldered to the inner and outer receptacles. Y

The numeral'. 38 designates a collar which is integral with the operating shaft, which collar is adapted to abrttagainst one of the standards. This collar or abutment in conjunction with the squared portion of the shaft upon Which'the larger gear Wheel is mounted, forms a recess into which the upper end of the standard extends, which construction prevents the lateral movement of the shaft in its bearings and does away with the necessity of drilling: the shaft for the insertion'v of pins or with the use of Wires or other device for preventing lateral movement. The construction is such that the parts may be readily and cheaply assembled, since obviously it is only necessary to mount the gear Wheel upon the shaft, place the shaft in its bearings, with the abutments on either side of one of the standards, and secure the clamp yoke in place, thus keeping all of the parts'in their proper relative position.

In operation, the butter is first broken or cut into lumps or pieces, preferably of small size and placed in the innerpvessel or receptacle, which I call the mixing chamber, and

onepint of milk is added thereto. Warm Water is then placed in the space around the mixing chamberor in what I term the heating chamber and the mixer is rotated. The heat of the Water gradually warms` the butter and milk, uniformly and increasingly and the rotary mixer is in the meantime rotated causing rapid agitation of the milk and butter, which is continued until a permanei'it and stable emulsion of the milk and butter is effected.v The construction of the machine is such that after the heat of the Water in the heating chamber has been utilized to soften the butter and bring it to condition for agi tation the Whole apparatus may beI placed under a faucet and cold water allowed to run intov the outer' cylinder, displacing the Warm '.Waterybr lowering the temperature thereof, during the operation ofthe machine, Which voperation is continued until the product .is brought to a satisfactory consistency, when it is-removed from the apparatus and used as ordinary or standard butter is used. The product is suoli that it maybe refrigerated and hardened as in the case of ordinary butter. A proper amount of coloring matter, if desired, may be added to the product, and it is preferable to add the coloring matter during agitation, as obviously the color will be more uniformly distributed throughout the mass. v
